<p align=center><b>Release 4.0: Java CLASSPATH environment variable</b></p>
<p>The Berkeley DB Java class files are now packaged as jar files.  In the 4.0
release, the <b>CLASSPATH</b> environment variable must change to
include at least the <b>db.jar</b> file.  It can optionally include
the <b>dbexamples.jar</b> file if you want to run the examples.  For
example, on UNIX:</p>
<blockquote><pre>export CLASSPATH="/usr/local/BerkeleyDB.4.7/lib/db.jar:/usr/local/BerkeleyDB.4.7/lib/dbexamples.jar"</pre></blockquote>
<p>For example, on Windows:</p>
<blockquote><pre>set CLASSPATH="D:\db\build_windows\Release\db.jar;D:\db\build_windows\Release\dbexamples.jar"</pre></blockquote>
<p>For more information on Java configuration, please see
<a href="../../ref/java/conf.html">Java configuration</a> and
<a href="../../ref/build_win/intro.html">Building for Windows</a>.</p>
